After a long and brave battle with cancer, Diem Browndied on Friday, Nov. 14, at the age of 32. MTV released a statement shortly after the Challenge star's passing, along with members of the Challenge and MTV community.

"MTV is tremendously sad to hear the news that Diem Brown has lost her long battle with cancer," the network told Us Weekly in a statement. "We send our deepest condolences to her family and friends. Diem was a true fighter and brought passion to everything she touched. We will miss her."

After overcoming the disease in 2006 and again, in 2012, the reality star was diagnosed with cancer for the third time in summer 2014. Still, Brown's fierce fight to survive continued to inspire many. In one of her final tweets, she wrote: "Whatever option I have to LIVE I'm grabbing! …No is not an option."

Former Challenge stars took to their social media accounts on Friday to react to the news.

"I have soo many wonderful, positive memories of Diem," MTV veteran Long tells Us. "I loved her spirit, her positivity, and her never ending "fight to live" attitude. She was the type of person that truly could light up a room, and also made everyone in that room feel important and special. She touched so many people in her short time on earth and i will miss her. My heart is heavy today and I hope everyone remembers her spirit, her smile, and never give up attitude. #LoveForDiem."

"Now, you are our heavinly angel. I see you dancing in heaven with your mother and grandmother. I promise to live the best life possible for both of us. Thank you for teaching me grace, faith, tenacity and for the gift of Medgift.com You and I will never end. You are my true, dear love."

Brown's close friend and MTV costar shared an Instagram video of the star, writing: "From shock and tears…. to smiles… This is @diembrown This is off the show…Straight pure dancing happiness and full of life. THIS is the Diem i know. There is no 'losing the fight' or 'losing the battle' to cancer. Please dont ever think or say that. She has done nothing but WIN with her life. She is an angel put here for us to teach us lessons. Diem has inspired strength to those who felt weak. She has reached out a hand to those who felt alone. She created MEDGIFT and left a beautiful legacy through her passion for helping others. She has shown all of us how to come together in prayer and love. What she has left us is the biggest gift in the world. We are sad because this heart of life got taken away from us too soon…. But we should celebrate what she has done. Celebrate her life. Be thankful for what she has taught us through her struggles. Know that life and health are never guaranteed. Tell those close to you that you love them. Be thankful for all the little things. Diems life, struggles, and death all had a purpose. Take everything she has taught you and be a better person for it. Prayers to her family. Diem is truly dancing with the stars now. All my love. Thank you Diem for reaching out to a lonely weirdo for a thanksgiving meal all those years ago. You changed my life more than you could ever know. I will pass along your kindness in your honor. Love you. You are and always will be a Warrior."
